For racers and serious tuners, the 3Racing M3 x 6mm AL7075 flat head hex screws supply a lightweight fastening option that fits tight setups. The AL7075 alloy keeps mass down while providing consistent mechanical behavior under typical race conditions.
AL7075 is chosen for its favourable strength to weight characteristics, making these screws useful when optimising a vehicle for lap time and handling. They are best applied to non-critical structural locations where weight savings aid dynamic response.
The M3 x 6mm size suits a broad array of mounting points encountered during tuning sessions, from body and sensor mounts to trim and light brackets. When adjusting setups, pair these screws with the correct hex driver and light thread retention where vibration is a concern.
